  • *Key variable for further primary treatment data.

  • †Only available options for patients with additional treatment chosen.

  • ‡Enriched with data from the Patient Register for those patients with missing date in the SNRUBC.

  • §Data available in the primary treatment form until 2016 to avoid double registration, as these data also are collected in the radical cystectomy form.
